user207924 asked:
I am trying to pass call via sip phone and I was success when I tried for the first time but after that I can’t connect the call showing the message below. Can any one give me a solution why this happening, if the configuration is not ok then how I could successfully call for the 1st time. If so then what is the problem?
My configuration is below
Sip.conf
My answer:
You dialed extension 10001, but it is engaged (busy). Hang up that phone and try again.
